The N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention can be produced, for example, by the following process. ##STR3## wherein R¹, R², R³, R⁴, R⁵ and Y are as defined above and Z is a halogen atom.

The N-substituted phenylcarbamic acid derivative of the general formula (I) can be produced by reacting a compound of the general formula (III) with a compound of the general formula (II) in the presence of a base or a silver compound, and an inert solvent.

As the inert solvent usable in this reaction, any inert solvent may be used so long as it does not markedly inhibit the progress of the reaction. There may be used, for example, alcohols such as isopropanol, tert-butanol, diethylene glycol, etc.; ketones such as acetone, methyl ethyl ketone, cyclohexanone, etc.; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, monoglyme, diglyme, etc.; halogenated hydrocarbons such as dichloroethane, chloroform, carbon tetrachloride, tetrachloroethane, etc.; aromatic hydrocarbons such as benzene, chlorobenzene, nitrobenzene, toluene, etc.; nitriles such as acetonitrile, etc.; dimethylformamide; dimethyl sulfoxide; and water. These inert solvents may be used singly or as a mixture thereof.

Two-phase reaction can be carried out as the above reaction by using water and a water-insoluble inert solvent. In this case, there can be used phase transfer catalysts such as triethylbenzylammonium chloride, trioctylmethylammonium chloride, etc.

As the base used in the reaction, an inorganic base or an organic base may be used. As the inorganic base, there may be used, for example, carbonates or hydroxides of alkali metal atoms or alkaline earth metal atoms, such as sodium carbonate, potassium carbonate, calcium carbonate, sodium hydrogencarbonate, sodium hydroxide, potassium hydroxide, calcium hydroxide, etc., and hydrides of alkali metal atoms, such as lithium hydride, sodium hydride, etc. As the organic base, there may be used, for example, alkoxides of alkali metal atoms, such as sodium methoxide, potassium tertbutoxide, etc., diethylamine, triethylamine, pyridine, and benzyltrimethylammonium hydroxide. These bases may be used singly or as a mixture thereof. The amount of the base used may be properly chosen in the range of 1 mole to excess moles per mole of the compound of the general formula (III).

As the silver compound usable in the reaction, silver oxide, for example, may be used. The amount of the silver compound used may be properly chosen in the range of 1 mole to excess moles per mole of the compound of the general formula (III).

Since the reaction is an equimolar reaction, it is sufficient that the compound of the general formula (III) and the compound of the general formula (II) are used in equimolar amounts, though either of them may be used in excess.

The reaction temperature is properly chosen in the range of -70° C. to the boiling point of the inert solvent used. It is preferably -40° C. to room temperature.

Although the reaction time is varied depending on the reaction temperature, the scale of reaction, etc., it is usually chosen in the range of 30 minutes to 48 hours.

After completion of the reaction, the desired compound is isolated from the reaction mixture by a conventional method, and if necessary, purified by column chromatography, recrystallization, etc., whereby the N-substituted phenylcarbamic acid derivative of the general formula (I) can be produced.

The hydroxyamine is reacted with a compound of the general formula (XI) in the presence of a base after or without isolation of the hydroxyamine to obtain a compound of the general formula (X). This compound (X) is reacted with a compound of the general formula (VIII) in the presence of a base after or without isolation of the compound (X) to obtain a compound of the general formula (IX). This compound (IX) is reacted with a halogenating agent under light irradiation after or without isolation of the compound (IX), whereby the compound of the general formula (III) can be produced. ##STR5## wherein, R¹, R², R³, R⁴, R⁵, Y, Z and Z¹ are as defined above , and R⁶ and R⁷, which may be the same or different, are hydrogen atoms, (C₁₋₆)alkyl groups, (C₃₋₆)cycloakyl groups, unsubstituted phenyl groups, or substituted phenyl group having 1 to 5 substituents which may be the same or different and which are selected from the group consisting of halogen atoms, cyano group, nitro group and (C₁₋₆)alkyl groups, R⁶ and R⁷ being able to be taken together to represent a (C₂₋₆)alkylene group.

A compound of the general formula (IV) is reacted with a halogenating agent in the presence or absence of an inert solvent to obtain a compound of the general formula (V). The compound (V) is reacted with a compound of the general formula (II) in the presence of an inert solvent and a base or a silver salt after or without isolation of the compound (V) to obtain a compound of the general formula (VI). The compound (VI) is reacted with a compound of the general formula (VII) in the presence or absence of an inert solvent and in the presence of a base after or without isolation of the compound (VI) to obtain an N-substituted phenylcarbamic acid derivative of the general formula (I-1). The derivative (I-1) is reacted with a compound of the general formula (VIII) in the presence or absence of an inert solvent and in the presence of a base after or without isolation of the derivative (I-1), whereby an N-substituted phenylcarbamic acid derivative of the general formula (I) can be produced.

3 General formula (VI)→general formula (I-1)

As the inert solvent and the base which are usable in this reaction, there can be used, for example, the inert solvents and the bases, respectively, exemplified in production process 1. The compound of the general formula (VII) may be used in excess to serve also as the inert solvent.

The amount of the base used may be properly chosen in the range of 1 mole to excess moles per mole of the compound of the general formula (VI).

Since the reaction is an equimolar reaction, it is sufficient that the compound of the general formula (VI) and the compound of the general formula (VII) are used in equimolar amounts, though either of them may be used in excess.

The reaction temperature is preferably in the range of 0° C. to the boiling point of the inert solvent used, and is more preferably a temperature near room temperature.

Although the reaction time is varied depending on the reaction temperature, the scale of reaction, etc., it is chosen in the range of several minutes to 24 hours.

After completion of the reaction, the desired compound is isolated from the reaction mixture containing the desired compound by a conventional method, and if necessary, purified by column chromatography, etc., whereby the N-substituted carbamic acid derivative of the general formula (I-1) can be produced.

The desired compound obtained by the reaction may be subjected to the subsequent reaction without isolation.

4 General formula (I-1)→general formula (I)

The N-substituted carbamic acid derivative of the general formula (I) can be produced by carrying out this reaction in a manner similar to the synthesys of the general formula (IX) described in the production process 1. The reaction temperature is preferably in the boiling range of the inert solvent used.

Typical compounds as the N-substituted carbamic acid derivatives of the general formula (I) produced by production processes 1 and 2 are listed in Table 3 but they are not intended in any way to limit the scope of the present invention.

The N-substituted phenylcarbamic acid derivatives of the general formula (I) of the present invention are useful as agricultural and horticultural fungicides and are very effective in controlling various diseases, for example, rice blast (Pyricularia oryzae), rice sheath blight (Rhizoctonia solani), rice helminthosporium leaf spot (Cochiobolus miyabeanus), powdery mildew of various host plants, such as powdery mildew of barley and wheat (Erysiphe graminis), oats crown rust (Puccinia coronata), rust of other plants, tomato late blight (Phytophthora infestans), late blight or Phytophthora rots of other plants, downy mildew of various plants, such as cucumber downy mildew (Pseudoperonospora cubensis) and grape downy mildew (plasmopara viticola), apple scab (Venturia inaequalis), apple alternaria leaf spot (Alternaria mali), pear black spot (Alternaria kikuchiana), and citrus melanose (Diaporthe citri).

The agricultural and horticultural fungicide of the present invention has a marked fungicidal effect on the above-exemplified diseases which damage paddy field crops, upland crops, fruit trees, vegetables, other crops, flowers and ornamental plants, and the like. Therefore, the desired effects of the agricultural and horticultural fungicide of the present invention can be obtained by applying the fungicide to the paddy field water, stalks and leaves of fruit trees, vegetables, other crops, flowers and ornamental plants, soil, etc., at a season at which the diseases are expected to occur, before their occurrence or at the time when their occurrence is confirmed.

When the N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention is used as an agricultural and horticultural fungicide, it is generally prepared into conveniently usable forms according to an ordinary manner for preparation of agrochemicals.

That is, the N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention and, optionally, an adjuvant are blended with a suitable inert carrier in a proper proportion and prepared into a suitable preparation form such as a suspension, emulsifiable concentrate, soluble concentrate, wettable powder, granules, dust or tablets through dissolution, dispersion, suspension, mixing, impregnation, adsorption or sticking.

The inert carrier used in the present invention may be either solid or liquid. As the solid carrier, there can be exemplified soybean flour, cereal flour, wood flour, bark flour, saw dust, powdered tobacco stalks, powdered walnut shells, bran, powdered cellulose, extraction residue of vegetables, powdered synthetic polymers or resins, clays (e.g. kaolin, bentonite, and acid clay), talcs (e.g. talc and pyrophyllite), silica powders or flakes (e.g. diatomaceous earth, silica sand, mica and white carbon, i.e. synthetic, high-dispersion silicic acid, also called finely divided hydrated silica or hydrated silicic acid, some of commercially available products contain silicate as the major component), activated carbon, powdered sulfur, powdered pumice, calcined diatomaceous earth, ground brick, fly ash, sand, calcium carbonate powder, calcium phosphate powder and other inorganic or mineral powders, chemical fertilizers (e.g. ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and ammonium chloride), and compost. These carriers may be used alone or as a mixture thereof.

The liquid carrier is that which itself has solubility or which is without such solubility but is capable of dispersing an active ingredient with the aid of an adjuvant. The following are typical examples of the liquid carrier and can be used alone or as a mixture thereof. Water; alcohols such as methanol, ethanol, isopropanol, butanol and ethylene glycol; ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone and cyclohexanone; ethers such as ethyl ether, dioxane, Cellosolve, dipropyl ether and tetrahydrofuran; aliphatic hydrocarbons such as kerosene and mineral oils; aromatic hydrocarbons such as benzene, toluene, xylene, solvent naphtha and alkylnaphthalenes; halogenated hydrocarbons such as dichloroethane, chloroform, carbon tetrachloride and chlorobenzene; esters such as ethyl acetate, diisopropyl phthalate, dibutyl phthalate and dioctyl phthalate; amides such as dimethylformamide, diethylformamide and dimethylacetamide; nitriles such as acetonitrile; and dimethyl sulfoxide.

The following are typical examples of the adjuvant, which are used depending upon purposes and used alone or in combination in some cases, or need not to be used at all.

To emulsify, disperse, dissolve and/or wet an active ingredient, a surfactant is used. As the surfactant, there can be exemplified polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene higher fatty acid esters, polyoxyethylene resinates, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monooleate, alkylarylsulfonates, naphthalenesulfonic acid condensation products, ligninsulfonates and higher alcohol sulfate esters.

Further, to stabilize the dispersion of an active ingredient, tackify it and/or bind it, there may be used adjuvants such as casein, gelatin, starch, methyl cellulose, carboxymethyl cellulose, gum arabic, polyvinyl alcohols, turpentine, bran oil, bentonite and ligninsulfonates.

To improve the flowability of a solid product, there may be used adjuvants such as waxes, stearates and alkyl phosphates.

Adjuvants such as naphthalenesulfonic acid condensation products and polycondensates of phosphates may be used as a peptizer for dispersible products.

Adjuvants such as silicon oils may also be used as a defoaming agent.

The content of the active ingredient may be varied as required. In dusts or granules, the suitable content thereof is from 0.01 to 50% by weight. In emulsifiable concentrates or flowable wettable powders, it is also from 0.01 to 50% by weight.

The agricultural and horticultural fungicide containing the N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention as an active ingredient is used to control various diseases in the following manner. That is, it is applied to a crop on which the diseases are expected to occur, or a site where the occurrence of the diseases is undesirable, as it is or after being properly diluted with or suspended in water or the like, in an amount effective for control of the diseases.

The applying dosage of the agricultural and horticultural fungicide containing the N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention as an active ingredient is varied depending upon various factors such as a purpose, diseases to be controlled, a growth state of a plant, tendency of disease occurrence, weather, environmental conditions, a preparation form, an application method, an application site and application time. It may be properly chosen in the range of 0.1 g to 1 kg (in terms of the active ingredient) per 10 ares depending upon purposes.

The agricultural and horticultural fungicide containing the N-substituted phenylcarbamic acid derivative of the general formula (I) of the present invention as an active ingredient may be used in admixture with other agricultural and horticultural fungicides in order to expand both spectrum of controllable diseases and the period of time when effective applications are possible or to reduce the dosage.
